Plastic pipe tools and cutters
Press, back in late 60's,Dupont came out with a pipe for
natural gas systems. And had all kinds of tools to go with
this new method back then. They had a very small pipe
cutter for cutting 5/8 pipe. As you stated, you must have
the right cutter wheel and they make all kinds, Cast Iron,
Steel, Etc. Very thin and sharp wheel and Like Al says
I now when It is sharp. I tried it back then and had used
it every since. Now if is just have one to make, I have the
Buck Electrician's knife in my pocket and it stays sharp.
But if I am going to make up some Jumpers and new run
to tower, I get the cutters out. They are not any longer
than 2 1/2" at the most and weigh nothing.I use the Pipe
cutter, like a limb trimmer but miniature to cut coax It
has a half circle to put the pipe in to cut it. The use the
wheel of do the other. For me it works super.
Yes there are a lot that do not need to try this method.
And Also, I have run Alpha's and Henrys thru it for
nearly 30 years. But you can look at it when U cut it
and tell if you did a good job, if not, lick the calf again/
